Point : an undefined term in geometry, it names a location and has no size
Line : an undefined term in geometry, a line is a straight path that has no thickness and extends forever
Plane : an undefined term in geometry, it is a flat surface that has no thickness and extends forever
Segment : a part of a figure cut off by a line or plane intersecting it in particular
Ray : a part of a line that starts at an endpoint and extends forever in one direction
Angle : a figure formed by two rays with a common endpoint
Vertical Angles : each of the pairs of opposite angles made by two intersecting lines
Adjacent Angles : two angles are adjacent if they have a common side and a common vertex and don't overlap
Linear Pair : two angles that are adjacent and supplementary
Complementary Angles : either of two angles whose sum is 90
Supplementary Angles : either of two angles whose sum is 180
Polygon : a plane figure with at least three straight side and angles, and typically five or more
Concave : one or more lines that contain a side also contain a point on the interior
Convex Polygon : no line that contains a side of the polygon also contains a point on the interior
Equilateral : all sides are congruent
Equiangular : all angles are congruent
Regular Polygon : polygons that are both equilateral and equiangular
Triangle : a plane figure with three straight sides and three angles
Quadrilateral : a shape with 4 sides
Pentagon : a shape with 5 sides
Hexagon : a shape with 6 sides
Septagon : a shape with 7 sides
Octagon : a shape with 8 sides
